The answer is "coal takes hundreds of millions of years to form." None of the other answer choices are true. 

Fossil fuel is a general term for crude oil, coal, natural gas, or heavy oils. These fuels were initially large deposits of organic material that were transformed into combustible materials. This happened because of exposure to heat and pressure in the earth's crust over hundreds of millions of years. Fossil fuels are a nonrenewable resource, but they make up the majority of our energy production.

Coal can be extracted from the earth either by surface mining or underground mining. Once coal has been extracted, it can be used directly (for heating and industrial processes) or to fuel power plants for electricity.

Extracting crude oil normally starts with drilling wells into an underground reservoir. When an oil well has been tapped, a geologist will note its presence. Often many wells (called multilateral wells) are drilled into the same reservoir.

Natural gas is most commonly extracted by drilling vertically from the Earth's surface. Hydraulic fracturing, horizontal drilling, and acidizing are processes to expand the amount of gas that a well can access.

The answer is "prehistoric algae and zooplankton whose remains settled on the bottom of an ocean or lake."

The answer is "all of these." Fracking can cause pollution of surface and groundwater, sedimentation of streams from construction of roads and well pads, dewatering of streams, and displacement of wildlife.

The answer is "sedimentary rock containing remains of dead organisms from millions of years ago."

The answer is "Texas" because Texas has many more drilling sites than most states.
